It is important to know how to tell if your dog has fleas so that you can get rid of these parasites as soon as you can. Animal flea infestation has been reported to be one of the most dreaded scenarios of pet owners, especially in warm climates and during the summer months. Fleas are small, blood-sucking, infection-transmitting insects that prefer hot and humid temperatures and often referred to as a “summer problem,” however, fleas can be a problem year round.
Flea infestation can occur either through direct contact with other flea-infested animals or through contact with fleas in the environment. As a result, dogs living in hot, humid, and outdoor environments tend to be more exposed to fleas. Also, because fleas hate light, they can often be found in damp dark areas.
Fleas multiply rapidly and it is important to look out for signs that they may be lurking somewhere near you.
What Are Fleas?
Fleas are small bugs that reach up to ¼ inch in length. This means that to the naked eye, they can be very hard to see. They are red or brown in color and they move very quickly but cannot fly. Fleas look like fat oval bugs with hard bodies. Usually, by the time you see them, they have jumped away from you.
What fleas eat depends on what stage of development they are in. The larvae don’t eat blood, instead, they eat skin cells, flea droppings, dead animals, feces or any other organic matter they can find.
Adult fleas tend to feed on blood once daily or occasionally, once every two days, and are equipped with the ability to ingest over fifteen times their weight in blood from their host.
Check for Fleas
Since fleas love warm environments, when you are checking your dog for fleas look in warm areas such as the armpits and groin. Another area fleas really like is the rear end. Often you can find them on your dog’s back and around the tail. With a mild infection, you will need to part the hair and closely examine the skin for signs of fleas, eggs, and flea dirt. In severe cases of fleas, you do not have to look too hard as you can sometimes see them on top of the dog’s skin or jumping off of them.
To help you find fleas on your dog, you can use a flea comb. These combs have very fine teeth allowing you to catch fleas and flea eggs in the comb.
If your examination is inconclusive and you are unsure if your dog has fleas, you can go to your veterinarian for help. The veterinarian will perform a full physical exam and tell you in no time. The veterinarian can also guide you through the process of treating fleas on your dog, preventing flea infestations, and treating skin infections or parasites caused by fleas. They can also offer advice on treating the environment if needed.
Signs of Fleas on Dogs

The process of itching if gone on too long can lead to damaging the skin barrier and causing scabs, scratches, sores, hotspots, and other wounds. This is referred to as dermatitis secondary to fleas. In addition, some dogs are very sensitive to flea bites and can even be allergic to the proteins in the flea’s saliva. This can cause an allergic reaction making the itching and skin infection worse. This is called flea allergy dermatitis. Other signs of a flea infection includes the presence of flea dirt (flea poop) or flea eggs on or around the dog, significant blood loss, or anemia (for chronic cases or in cases of heavy flea infestation), and tapeworm infestation.

They begin to lay eggs 36-48 hours after they had a feeding.
Flea Dirt on Dogs

Frequently Asked Questions
My Dog is Always Scratching but Doesn’t Have Fleas
While compulsive chewing, licking, and scratching behaviors in dogs are often associated with a flea infestation, this is not always the case. Other causes for this behavior include allergies, environment (mold, pesticides, pollen, or soap), [amazon link=”B01EKSPB92″ link_icon=”amazon” /], fungal infections, hormonal imbalances, pain, or stress (anxiety, boredom). Whatever the case, it is worth talking to your veterinarian about these factors after you have made sure your dog doesn’t truly have fleas.

When a dog wag’s his tail, it might touch plants, bushes, or something dirty on the ground. This can lead to skin irritations on the tail which can instigate itch and secondary dermatitis.

Flea Bites on People
Dog Fleas on Humans
We’ve come to know that when we get a flea bite, we can let the itching subside and disappear on its own ranging from as little as a few hours to a few days. But just like our pets, we are vulnerable to flea bite allergies which can be lethal if ignored. While we may easily brush off flea bites, it is possible to get infections or allergies from these bites. Learning how to tell if your dog has fleas can definitely help prevent fleas from transferring to humans.
Common symptoms of flea allergic reactions include swelling of lips or tongues, chest pains, dizziness, difficulty breathing, and nausea. Meanwhile, if your flea bite gets infected you may experience symptoms which include intolerable pain on the bitten area, extensive redness, and swollen glands.
Flea Bites on Kids
As most children may not comprehend a flea bite when they get one, it is vital to prevent the possibility of them getting bitten. You may mistake a flea bite for chicken pox in your child, but you should note that flea bites do not blister like chicken pox.
Flea bites in children can pose a huge threat because an allergic reaction in children may be more fatal than in adults. Seek immediate attention if your child shows any signs of a flea bite allergy. Whether the reaction is allergic or not, encourage your child not to scratch as this may lead to an infection. Be wary and prevent flea bites because fleas can also transmit tapeworm and, in extreme cases, bubonic plague.
The Lifespan of a Flea
The problem with fleas is that once the adult flea lays its eggs on your dog, a vicious cycle of flea reproduction begins. Although a flea dies once it bites your dog, or it leaves after laying its eggs, the average lifespan of a flea is 30-90 days, so if left untreated, your dog will be harboring a new group of fleas every month to 3 months. An untreated flea allergy in your dog will result in scabs and unsightly hair loss, therefore it is vital to treat your dog periodically to prevent the onset of any flea problems. Fleas can also lay eggs in carpet or in dark or damp areas in your house. These eggs can hatch months later, causing another cycle of problems.
Dog Fleas vs Cat Fleas
Now, we’re all familiar with dog fleas. Cat fleas, on the other hand, are a totally different thing. Cat fleas are different from dog fleas, but regardless of their name, they can still affect dogs. And unfortunately, they can also affect humans.
There are many ways through which you can tell whether your dog has fleas or not. Fleas in dogs are very common these days and if you have the slightest hint that your dog might have fleas, be informed of the ways to get rid of the infestation. There are several things you can do which are very easy and you can even do them in the sanctity of your own home.
It goes without saying that a flea infestation is a serious problem especially if left unchecked. In addition to threatening the overall livelihood and survival of the infected dog(s), some fleas like the cat flea, Ctenocephalides felis, can affect cats, dogs, humans, and many other animals, equally posing a threat to their lives. Hence, early prevention, identification, and treatment of flea infestations are paramount.
